Objective To investigate the distribution of the traditional Chinese medicine(TCM)constitution types in the patients with nonspecific low back pain(NLBP)and to explore the correlation of the thickness of ligamentum flavum with the age,body mass index(BMI),gender,the presence of diabetes mellitus,and the grading of hypertension.Methods Sixty patients with NLBP admitted to Guangdong Second Traditional Chinese Medicine Hospital from January 2023 to June 2023 were selected as the study subjects.The TCM constitution types of the patients were identified,the thickness of the ligamentum flavum at lumbar vertebrae 4/5 segment(L4/5)disc level was measured by computerized tomography(CT)scanning,and the patients'age,genders,TCM constitution types,BMI,the presence or absence of diabetes mellitus,and hypertension grading were recorded.Correlation analysis and linear regression analysis were used for the exploration of the relevant influencing factors for the thickness of the ligamentum flavum of patients with NLBP.Results(1)The average thickness of ligamentum flavum in the 60 patients with NLBP was(2.60±0.72)mm.(2)The TCM constitutions of NLBP patients were classified into four types,of which blood stasis constitution was the most common,accounting for 21 cases(35.0%),followed by 19 cases(31.7%)of damp-heat constitution,12 cases(20.0%)of phlegm-damp constitution,and 8 cases(13.3%)of qi deficiency constitution.(3)The results of correlation analysis showed that BMI,gender,TCM constitution type and the presence or absence of diabetes mellitus had no influence on the thickness of ligamentum flavum in NLBP patients(P＞0.05),while the age and hypertension grading had an influence on the thickness of ligamentum flavum(P＜0.01).(4)The results of linear regression analysis showed that the age had an influence on the thickness of the ligamentum flavum(b = 0.034,t = 6.282,P＜0.01),while the influence of the hypertension grading had no influence on the thickness of the ligamentum flavum(P＞0.05).Conclusion The TCM constitution type of NLBP patients is predominated by blood stasis constitution,the thickness of ligamentum flavum is significantly affected by the age,and hypertension may be a potential factor affecting the thickness of ligamentum flavum.

Objective To observe the clinical efficacy of"triple-posture positive bone-setting"chiropractic manipulation combined with Tongluo Huoxue Formula for the treatment of lumbar spinal stenosis(LSS)with qi deficiency and blood stasis syndrome.Methods Sixty patients with LSS of qi deficiency and blood stasis type were randomly divided into trial group and control group,with 30 cases in each group.The trial group was treated with"triple-posture positive bone-setting"chiropractic manipulation(a chiropractic manipulation performed under the positive cooperation of the patients at three postures)combined with Tongluo Huoxue Formula,while the control group was treated with"triple-posture positive bone-setting"chiropractic manipulation combined with conventional western medicine.The course of treatment for the two groups covered 4 weeks.Before and after treatment,the patients of the two groups were observed in the changes of pain visual analogue scale(VAS)score,Japanese Orthopedic Association(JOA)score of lumbar function,Oswestry Disability Index(ODI)score,straight-leg raising test results and serum interleukin 6(IL-6)and C-reactive protein(CRP)levels.After treatment,the clinical efficacy and safety of the two groups were evaluated.Results(1)After 4 weeks of treatment,the total effective rate of the trial group was 96.67％(29/30)and that of the control group was 63.33％(19/30).The intergroup comparison(tested by Fisher's exact test)showed that the clinical efficacy of the trial group was significantly superior to that of the control group(P＜0.05).(2)After treatment,the lumbar function indicators of pain VAS scores and ODI scores in the trial group were significantly lower(P＜0.05),and the JOA scores were significantly higher than those before treatment(P＜0.05),while in the control group,only the ODI scores were significantly lower than those before treatment(P＜0.05).The intergroup comparison showed that the decrease of VAS and ODI scores and the increase of JOA scores in the trial group were significantly superior to those in the control group(P＜0.05 or P＜0.01).(3)After treatment,the Laseque s sign of the trial group was significantly improved compared with that before treatment(P＜0.05),while no significant improvement was presented in the control group(P＞0.05).The intergroup comparison showed that the improvement of Laseque's sign in the trial group was significantly superior to that in the control group(P＜0.01).(4)After treatment,the levels of serum inflammatory factors of IL-6 and CRP in the two groups were lower than those before treatment(P＜0.05),and the decrease of serum IL-6 level in the trial group was significantly superior to that in the control group(P＜0.05),but CRP level in the two groups after treatment did not differ from that before treatment,no statistically significant difference was shown between the two groups after treatment,either(P＞0.05).(5)The incidence of adverse reactions in the trial group was 6.67％(2/30)and that in the control group was 13.33％(4/30),and the intergroup comparison(by Fisher's exact test)showed that there was no significant difference between the two groups(P＞0.05).Conclusion The therapeutic effect of"triple-posture positive bone-setting"chiropractic manipulation combined with Tongluo Huoxue Formula exert certain effect for the treatment of LSS patients with qi deficiency and blood stasis syndrome,and it has more obvious advantages in improving the lumbar function,promoting the rehabilitation of the patients,and lowering the level of serum inflammatory factors than"triple-posture positive bone-setting"chiropractic manipulation combined with conventional western medication.

Objective: Clinical manifestations, imaging findings, pathologic features, and genetic mutations of Chinese adult patients with cerebrotendinous xanthomatosis (CTX) were analyzed in order to achieve a greater understanding of CTX that can improve early detection, diagnosis, and treatment. Methods: Clinical data including medical history, neurologic and auxiliary examinations, imaging findings, and genetic profile were collected for an adult patient with CTX admitted to the Sixth Medical Center of Chinese People's Liberation Army General Hospital in August 2020. Additionally, a systematic review of genetically diagnosed Chinese adult CTX cases reported in major databases in China and other countries was performed and age of onset, first symptoms, common signs and symptoms, pathologic findings, imaging changes, and gene mutations were analyzed. Results: The proband was a 39-year-old female with extensive, early-onset nervous system manifestations including cognitive dysfunction and ataxia. Systemic lesions included juvenile cataract and a tendon mass. Cranial magnetic resonance imaging revealed cerebral atrophy, symmetric white matter changes predominantly in the pyramidal tract, and lesions in the cerebellar dentate nucleus. A novel homozygous mutation in the sterol-27-hydroxylase (CYP27A1) gene (c.1477-2A>C) was identified. There were no family members with similar clinical presentation although some were carriers of the c.1477-2A>C mutation. The patient showed a good response to deoxycholic acid treatment. Totally there were 56 cases of adult CTX patients in China, mostly in East China (31/56, 55.4%), at a male-to-female ratio of 1.8 to 1. Multiple organs and tissues including nervous system, tendon, lens, lung, and skeletal muscle were affected in these cases. The most common neurologic manifestations were cognitive dysfunction (44/52, 84.6%) and ataxia (44/51, 86.3%). The cases were characterized by early onset, chronic progressive damage of multiple systems, long disease course, and delayed diagnosis, making the disease difficult to manage clinically and resulting in poor prognosis. The 2 most common genetic mutations in Chinese adult CTX patients were c.1263+1G>A and c.379C>T. Exon 2 of the CYP27A1 gene was identified as a mutation hot spot. Conclusions: Chinese adult patients with CTX have complex clinical characteristics, a long diagnostic cycle, and various CYP27A1 gene mutations. Early diagnosis and intervention can improve the prognosis of these patients.

Schistosomiasis was once heavily endemic in Jiangsu Province. Following the control efforts for several decades, schistosomiasis was almost eradicated in all endemic counties in Jiangsu Province in 1980, and transmission control was achieved in the province in 2011. According to the principle of “implementing the control measures with adaptation to local circumstances and guiding the control programs with classified interventions”, an integrated strategy with emphasis on the management of both infectious sources and snails has been recently employed for schitsosomiasis control in Jiangsu Province. In addition, a sensitive and highly effective surveillance system has been built and the application of novel techniques and information construction has been intensified to effectively interrupt the transmission of schistosomiasis in the Province. Transmission interruption of schistosomiasis was achieved in all endemic counties in Jiangsu Province. The paper summarizes the endemic situation of schistosomiasis, progress of schistosomiasis control, and major schistosomiasis control measures implemented during the stage of transmission interruption in Jiangsu Province.

OBJECTIVE: To explore the method and effect of ultrasound-guided suprascapular nerve block combined with acupuncture in the treatment of calcified tendinitis of rotator cuff. METHODS: From January 2015 to December 2017, total 30 patients with calcified tendinitis, including 23 cases of supraspinatus tendon, 5 cases of infraspinatus tendon and 2 cases of subscapular tendon, were treated with ultrasound-guided suprascapular nerve block combined with acupuncture. There were 7 males and 23 females, ranging in age from 36 to 71 years old, with an average of 51.6 years old. There were 17 cases on the right and 13 cases on the left. VAS pain score, Constant-murley score, UCLA score and X-ray examination were used to evaluate the clinical results before and after surgery. RESULTS: The mean follow-up was 14.3 months (6 to 30 months). The preoperative VAS score was 3.82±1.13, Constant-Murley score was 36.91±7.95 and UCLA score was 11.35±2.17. The final follow-up scores were 1.32±1.06, 90.61±2.89 and 33.22±1.51, respectively. The final follow-up scores were improved significantly(<0.05). CONCLUSIONS Conservative treatment of calcified rotator cuff tendinitis is ineffective. Suprascapular nerve block guided by ultrasound combined with acupuncture has a good therapeutic effect. It is a minimally invasive, economic, safe and effective method, which is worth promoting.

Objective:Compare the effects of 3 administration methods (tracheal perfusion, tail vein injection and aerosol inhalation) with bleomycin (BLM) in inducing pulmonary fibrosis in rats, in order to find out the optimal administration methods. Method:Eighty sprague-dawley (SD) male rats with SPF were randomly divided into aerosol inhalation blank group, single tracheal perfusion group(10 mg·kg^-1), multiple tracheal perfusion group(5 mg·kg^-1), single intravenous injection group(150 mg·kg^-1), multiple intravenous injection group(50 mg·kg^-1), single aerosol inhalation group (30 min)and multiple aerosol inhalation group(30 min). The mortality and body weight of rats in each group were observed at 7 d, 14 d and 28 d after the administration. And 28 days later after the administration, the lung coefficients of rats in each group were observed, paraffin sections were prepared, hematoxylin-eosin staining (HE) and Masson staining were performed, and the contents of hydroxyproline (HYP) and plasminogen activator inhibitor-1 (PAI-1) in lung tissues were detected by enzyme-linked immunosorbent assay (ELISA), so as to evaluate the alveoli inflammation and pulmonary fibrosis of rats in each group. Result:Compared with the aerosol inhalation blank group, the rats in the trachea perfusion group had the highest mortality among the drug treatment groups. The pulmonary coefficients of rats in the multiple intravenous injection group and the multiple inhalation group were significantly higher than those in the blank group(P<0.05,P<0.01). The multiple inhalation group was higher than the other model group and the single atomization model group. The results of HE and Masson staining showed thickening of pulmonary septum and higher degree of pulmonary interstitial fibrosis in tracheal perfusion group, intravenous injection group and multiple inhalation group. The degree of pulmonary fibrosis in the multiple inhalation group was more obvious than that in other groups. The results of ELISA showed that the levels of HYP and PAI-1 in lung tissues of rats in aerosol inhalation group and tracheal perfusion group were significantly higher than those in control group(P<0.05). The multiple inhalation group and the single atomization inhalation group were significantly higher than other modules. Conclusion:Bleomycin was inhaled repeatedly to establish pulmonary fibrosis model. The pathological injury and physiological indexes of the model rats were relatively stable, which conforms with the evolution process of pulmonary fibrosis.

Conclusion: Tanreqing inhalation solution has obvious antitussive, expectorant, antipyretic and anti-inflammatory effects, which is worthy of further development and promotion.

Objective:To observe effect of Zeqi Tang in intervening mice with orthotopic lung cancer model, in order to observe its anti-tumor mechanism. Method:An in situ mouse model of non-small cell lung cancer was established through intrapulmonary injection with 1×10⁵ LLC-luc cells. The model mice were intragastrically administered with Zeqi Tang(0.171 g·mL^-1) or normal saline for 35 days. Appearance (spirit, hair, appetite, sleep), survival period and Zeqi Tang anti-tumor effect were observed, weekly vital imaging was performed to detect the fluorescence signal in the lungs of mice. Flow cytometry was used to detect the NK cell content in the spleen of the model mice. CD107α was used to detect the degranulation of NK cells in the spleen of mice after administration of Zeqi Tang. Kromasil 100 5 C₁₈ column was used and eluted with acetonitrile-0.025%phosphoric acid in a gradient mode, with flow rate at 1.0 mL·min^-1, column temperature at 35℃ and detection wavelength of 265 nm, as to establish the fingerprint of Zeqi Tang. The fingerprints of 10 batches of samples was evaluated by using the Chinese Medicine Chromatographic Fingerprint Similarity Evaluation System Software (2012 Edition) recommended by the Chinese Pharmacopoeia Commission, in order to complete the quality control of Zeqi Tang. Result:Zeqi Tang could significantly inhibit the lung fluorescence signal of lung cancer in situ model mice and prolong the survival of mice(P<0.05, P<0.01). After the intervention with Zeqi Tang, the NK cells in the tumors increased significantly(P<0.01), and the degranulation of CD107α also increased significantly(P<0.01). Moreover, the HPLC-DAD fingerprint of Zeqi Tang showed a significant increase in the fingerprint similarity of 10 batches of lacquer soup aqueous extract. Moreover, the HPLC-DAD fingerprint of Zeqi Tang showed that the fingerprint similarity of 10 batches of lacquer soup aqueous extract was ≥ 0.9, indicating that small differences between the batches. Conclusion:Zeqi Tang may enhance the tumor growth and prolong the survival period of mice by up-regulating the number of NK cells in mice and enhancing their degranulation function. The evaluation of similarity of HPLC fingerprint of Zeqi Tang reflects the quality of lacquer soup to a certain extent, and can provide reference for further study.

Early diagnoses and treatment methods are being constantly improved, but cancer metastasis remains a main cause of mortality in malignant tumor patients. Lung is thought to be the organ most prone to distal metastasis among malignant tumors due to its unique physiological and pathological character. Tumor lung metastasis is unpredictable and may result in irreversible damages. Presently, no exact mechanism or specific targeting therapies are found. Depending on the unique theory system-treatment based on symptom differentiation, traditional Chinese medicine has made significant progress on controlling tumor lung metastasis, but its application methods and mechanism still need further study and exploration. More appropriate and idealized animal models are required as a studying medium. Therefore, the establishment of animal models to simulate lung metastasis of cancer patients has become the key to the study of tumor lung metastasis. In order to produce a better platform for investigating the pathogenesis, underlying mechanism, early diagnosis and therapeutics for tumor lung metastasis, and to provide reference for the selection and establishment of mouse lung metastasis model, this article would introduce the implementation, application and estimation of several common methods (tail vein injection, mammary fat pad orthotopic injection, tibia injection, tissue orthotopic implantation, transgenic mice and so on). Meanwhile, the development of mouse lung metastasis model still needs expanding of thoughts, rational and flexible utilization of existing models, and interdisciplinary cooperation to establish preferable animal models and make results more reliable.

Lung cancer is a common malignancy with a high morbidity and high mortality. Although chemoradiotherapy is still the main therapy, the side effects caused by radiotherapy and chemotherapy cannot be ignored. There is an urgent need to find a targeted anti-cancer compound with a low toxicity and strong effect. Therefore, a large number of natural product-derived compounds have received increasing attention for their anti-cancer effect. They are diverse in structure, rich in variety but simpler in composition than natural plants, with a clear efficacy. This facilitates research, and the enriched ingredients have stronger pharmacological effect and clinical efficacy than natural plants. Quinonoids are natural bioactive molecules that widely exist in more than 100 species of higher and lower plants, including naphthoquinones, phenanthrenequinones, benzoquinones and pyrenes. Most of them have anti-tumor effect. They are applied and studied in many cancers, especially lung cancer; and the mechanism of action involves multiple pathways, which play a role in promoting apoptosis, inhibiting proliferation, inducing autophagy, inhibiting angiogenesis and cell invasion and migration. When they are used in combination with other drugs, there is also an anti-tumor effect. With the development of researches, many synthetic quinonoid derivatives with similar structures also increase the diversity of anti-cancer steroids, and quinonoids have broad application prospects in lung cancer. On the basis of a large amount of literature, this article reviews current studies on the molecular mechanisms of antitumor activity of quinonoids, summarizes the common research targets with different effect, and analyzes the relationship between the pharmacological effects and anti-lung cancer effects of quinonoids, and proposes the direction of further research, so as to provide the reference for the follow-up research and development of other quinonoids.
